Testosterone undecanoate is used in androgen replacement therapy. It is specifically approved only for the treatment of hypogonadism. As an intramuscular injection, it is administered at a dosage of 1,000 mg once every 12 weeks. Conversely, oral testosterone undecanoate must be taken two or three times a day with food.
Side effects of testosterone undecanoate include symptoms of masculinization like acne, increased hair growth, voice changes, hypertension, elevated liver enzymes, hypertiglyceridemia, and increased sexual desire. The drug is a prodrug of testosterone, the biological ligand of the androgen receptor (AR) and hence is an androgen and anabolic steroid. It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy. Testosterone undecanoate is a testosterone ester and a prodrug of testosterone in the body. Because of this, it is considered to be a natural and bioidentical form of testosterone.
